Implications of a changing Arctic on summertime rates of air-sea CO2 exchange within the eastern Canadian ArcticBurgers, Tonya 21 December 2015 (has links)
The Arctic marine system is currently undergoing transition as a result of climate change. This study examines the effects of this transition on rates of air-sea CO2 exchange within the eastern Canadian Arctic. Continuous seawater pCO2 measurements revealed this area to be a strong summertime sink of atmospheric CO2. Total alkalinity and stable oxygen isotopes were utilized as freshwater tracers, revealing areas of significant sea ice melt and riverine inputs. Eastern Baffin Bay and Barrow Strait were found to be strongly influenced by sea ice melt, lowering seawater pCO2; whereas Kennedy Channel contained significant river discharge, raising seawater pCO2. Primary production in surface waters was low throughout the region, with the exception of Petermann Fjord where glacial ice melt likely transports nutrients to the surface. This region is anticipated to represent a weaker CO2 sink in the future, due mainly to predicted decreases in sea ice thickness and extent. / February 2016

Improved decision support within biocorrosion management for Oil and Gas water injection systemsStipaničev, Marko 27 August 2013 (has links) (PDF)
The objective of this work, achieved in the framework of the BIOCOR European Network, has been to provide the operators of Sea-Water Injection System (SWIS) with improved decision support. The implication of biological component on carbon steel corrosion was explored as well as the possible synergy with other elements (mechanical stress, material properties…). This work showed that biogenic sulphide production, a corrosion threat for steel, can have different origins in seawater. The production rate can determine kinetics and morphology of corrosion attack, which might be governed by the type of microorganisms present. The key parameters are the availability of electron acceptors and the surrounding environment temperature. Sulfate-Reducing Bacteria (SRB) exhibit more vigorous attack compared to sulfidogenic bacteria or genera Clostridium, both found in the studied SWIS. Microbial activity also affects the mineralization process naturally occurring on carbon steel surface leading to architectures composed of mixed iron (II) and (III) minerals such as iron sulfides, magnetite, iron oxyhydroxides, chukanovite and green rust (sulfated or carbonated) as well as calcareous deposits. Inner layers of these structures could possibly provide an anaerobic habitat for SRBs, where they can flourish by using sulfate from GR(SO42-) as a terminal electron acceptor for their dissimilatory respiration. This enables continuous degradation of steel. Finally, significance of material microstructure and impact of mechanical stress on corrosion processes was also recognized. Grain boundaries and inclusions are playing a role during the initial stage of corrosion attack. This impact can diminish during the immersion time. An elevated bacterial activity coupled with mechanical stress leads to an increase of material deterioration. However, the mechanisms are not different from those usually observed for unstressed steel. Moreover, sulfidogenic microbial activity does not seem to lead to a failure mechanism related to Stress Corrosion Cracking (SCC). In conclusion, the outcomes indicate the possible situations, which may (or may not) lead to breach the safe operating window for a given SWIS.
